Normal human left and right ventricular dimensions for MRI as assessed by turbo gradient echo and steady-state free precession imaging sequences

Purpose: To establish normal ranges of left ventricular (LV) and right ventricular (RV) dimensions as determined by the current pulse sequences. in cardiac magnetic resonance imaging (MRI). Materials. and Methods: Sixty normal subjects (30 male and 30 female; age range, 20-65) were examined; both, turbo gradient echo (TGE) and steady-state free precession (SS,FP) pulse sequences were, used to obtain contiguous short-axis cine data sets from the ventricular apex to the base of the heart. The LV,and RV volumes and LV mass were calculated by modified Simpson's rule. Results: Normal ranges were established and indexed to both body surface area (BSA) and height. There were statistically significant differences in-the measurements between the genders and between TGE and SSFP pulse sequences. For TGE the LV end-diastolic volume (EDV)/BSA (mL/m(2)) in males was 74.4 +/- 14.6 and, in females was 70.9 +/- 11.7, while in SSFP in males it was 82.3 +/- 14.7 and in females it was 77.7 +/- 10.8. For the TGE the LV mass/ BSA (g/m(2)) in males was 77.8 +/- 9.1 and in females it was 61.5 +/- 7.5, while in SSFP in males it was 64.7 +/- 9 3 and in females it was 52.0 +/- 7.4. For TGE the RV EDV/BSA (mL/ m(2)) in males was 78.4 +/- 14.0 and in females it was 67.5 +/- 12.7, while in SSFP in males it was 86.2 +/- 14.1 and in females it was 75.2 +/- 13.8. Conclusion: We have provided normal ranges that are gender specific as well as data that can be used for age-specific normal ranges for both SSFP and TGE pulse sequences.
